Grilled Zucchini, Baby Portabella Mushrooms and Chicken Breast

Off the grill tonight, zucchini, baby Portabellas and chicken breast. The zucchini had kosher salt, fresh cracked pepper and I sprayed them extra virgin olive oil. One of the mushrooms simply had Balsamic vinegar. The other two had chimichurri sauce (oil, vinegar, garlic, parsley and cilantro).
